=head1 DESCRIPTION |
| 41 |
|
|
|
| 42 |
|
|
The C<warnings> pragma is a replacement for the command line flag C<-w>, |
| 43 |
|
|
but the pragma is limited to the enclosing block, while the flag is global. |
| 44 |
|
|
See L<perllexwarn> for more information. |
| 45 |
|
|
|
| 46 |
|
|
If no import list is supplied, all possible warnings are either enabled |
| 47 |
|
|
or disabled. |
| 48 |
|
|
|
| 49 |
|
|
A number of functions are provided to assist module authors. |
